Water Conservation and Management

The axial pump is a pump in which fluid flows axially to the rotation of the propeller. In Axial flow, the fluid flows parallel to the axis of rotation, as in a turbine. Axial flow pump contains a propeller or centrifugal impeller in the casing. Axial Flow pump is preferred for flood control and irrigation applications.

• Water is an very important liquid present in the living world. Life has began in the water and the living organism cannot part from the water. They depend on water in major ways to continue their bodies major function.
• 70% of the animal body is made up of water. It helps in maintaining or maintains many functions of the body. Such as digestion and absorption of food which take place in the alimentary canal where the digested food is broken down with the help of water molecules into small absorbable component. Also after digestion some of the nutrients are absorbs along with water in the  digestive tract.
• As water itself talks long time to change its temperature compared to its surrounding it also helps in maintaining body temperature as the body is made up of 70% water and so the temperature of body is maintained. Where as the process of sweating and transpiration also release water to cool of the body when ever the temperature of body rises.
• Water is known to be an universal solvent as it can solve any polar solute such as salt, sugar, gases etc in the water, water molecule also form electrostatic bonds with ions who are partially soluble in pure water. Non polar solute are very poorly soluble in water.
• Also water is an important medium for reproduction. As the gametes that are required for the sexual reproduction cannot be produced with the water medium.
• Water works as the shock absorber for the brain and the spinal cord and protects them from the mechanical shock. As water is present in the fluid surrounding these organs.
  
• Therefore water is required for one function or the other in the body.
• Therefore the correct answer is option D 
  

The water that we get from sources such as taps, hand pumps, wells and ponds is not pure. It may contain several salts dissolved in it. Small amounts of mineral salts are naturally present in it. This water is thus a good conductor of electricity.

Groundwater moves through soil and rocks, picking up pollution along the way. Plastic trash can affect groundwater quality, especially if you dispose of it improperly. It reduces the percolation of water as it comes in the way as water moves through soil.

While water covers most of the Earth, only about 1 percent of it is accessible, fresh, and safe for human consumption.

A short shower typically uses significantly less water than filling a bathtub, which requires a large volume of water to fill.

Leaving the tap running while brushing teeth allows gallons of water to go down the drain unnecessarily; turning it off saves this water.

Modern dishwashers are designed to be water-efficient and generally use less water than washing dishes by hand under a running tap.

Average daily water usage for a family of four in many developed regions is estimated to be around 400 gallons, including indoor and outdoor use.

Using a sponge and a bucket instead of a running hose can save approximately 5 gallons of water per minute.

Watering the lawn in the early morning reduces water loss due to evaporation, as temperatures are cooler and winds are generally calmer.

The average daily water usage in many Sub-Saharan African regions is significantly lower than 50 gallons, often closer to 5 gallons per person.

The vast majority of water-related deaths occur in developing nations due to lack of sanitation and clean water infrastructure.

While we use large amounts of water for various purposes, only a very small percentage of total water usage is for direct consumption (drinking/cooking).
